Re: TBI vs Carb
under the brake booster if the fuel pump harness connector ( 2 wires)....power and ground.
i just went through this. all factory ECU & WIRING is gone.
the wiring looks intimidating as it routes in and out of the ecu, to the engine and back into cab for some gauge interface.
most is redundant, if chase a schematic, the gauges have their own sensors, the ecu has its own, but talks through the check engine light.
not much to these trucks pre 95.
